Instances

PixmapClass Pixmap

type Bitmap = Pixmap Source

A Bitmap is a special Pixmap in that the number of bits per pixel is one, that is, a pixel is either set or unset. Whenever a function expects a Bitmap, a Pixmap of depth one must be supplied.

Constructors

pixmapNew Source

Arguments

:: DrawableClass drawable
=> Maybe drawable	`drawable` - drawable supplying default values for the pixmap
-> Int	`width` - width of the pixmap
-> Int	`height` - height of the pixmap
-> Maybe Int	`depth` - depth of the pixmap
-> IO Pixmap

Create a new pixmap.

If drawable is Nothing, the depth of the pixmap is taken from the depth parameter, otherwise the pixmap has the same depth as the Drawable specified by drawable. Therefore, at least one of drawable and depth must not be Nothing.

Note that in Gtk+ 2.0 the drawable can only be a DrawWindow, not an arbitary Drawable.
